• Initial Assessment & Referral for Other Mental Health Concerns (e.g., OCD, PTSD, Eating Disorders, Bipolar Disorder, Psychosis): Ensuring individuals with complex or acute mental health needs are connected with the right resources and expertise for effective and safe management.

Joint Muscle Pain

• Fibromyalgia & Other Widespread Chronic Pain Syndromes - Primary Care Diagnosis & Multimodal Management: A supportive, holistic, and patient-centered primary care approach to helping individuals manage the complex and often debilitating symptoms of fibromyalgia (widespread pain, profound fatigue, sleep disturbance, cognitive dysfunction - 'fibro fog', mood disturbances), aiming to improve daily function, reduce pain interference, and enhance overall quality of life.
• Mechanical Low Back & Neck Pain (Acute, Subacute, Chronic - Uncomplicated): Helping patients understand the nature of their mechanical spinal pain, empowering them with self-management techniques, and discouraging reliance on passive treatments or unnecessary imaging for uncomplicated cases, in line with clinical practice guidelines.
• Polymyalgia Rheumatica (PMR) - Diagnosis, Management & Monitoring (Often with Rheumatology Co-Management): Long-term management of PMR involves a very slow and gradual tapering of corticosteroids over 1-2 years (or longer), carefully monitoring for clinical relapse (recurrence of symptoms) and adjusting steroid dose accordingly. Also includes monitoring for and managing potential corticosteroid side effects (e.g., osteoporosis - bone protection with calcium/vitamin D, bisphosphonates if needed; hyperglycemia; hypertension; weight gain; mood changes; skin fragility).
• Gout & Pseudogout (Crystal Arthropathies) - Acute Attack Management & Chronic Prevention Strategies: Providing long-term management strategies for chronic gout to prevent recurrent attacks and complications (e.g., tophi, chronic gouty arthropathy, kidney stones), including detailed lifestyle advice (dietary modifications - reducing purine-rich foods such as red meat/organ meats/shellfish, limiting alcohol especially beer and spirits, avoiding sugary drinks/high-fructose corn syrup; hydration; weight management if overweight/obese) and initiating/managing urate-lowering therapy (ULT) such as allopurinol or febuxostat to achieve and maintain target serum uric acid levels (typically <360 µmol/L or <300 µmol/L if tophi present). Monitoring for medication side effects, adherence, and regular serum uric acid levels.

Adult Common Health Issues

• Restless Legs Syndrome (RLS) - Initial Assessment & Management: Helping patients manage the uncomfortable sensations and sleep disruption associated with RLS.

Referral to hematology for complex or unexplained anemia.
• Venous Insufficiency & Varicose Veins (Conservative Management & Lifestyle Advice): Initial assessment and conservative management of symptoms related to chronic venous insufficiency (CVI) and varicose veins, such as leg aching, heaviness, swelling (edema), skin changes (e.g., hyperpigmentation, lipodermatosclerosis, venous eczema), and uncomplicated superficial thrombophlebitis. Ruling out deep vein thrombosis (DVT) if acute unilateral swelling/pain.

Dermatological Skin Conditions

• Eczema (Atopic Dermatitis), Contact Dermatitis & Seborrheic Dermatitis: Helping patients control flare-ups of itchy, red, inflamed, and dry skin, maintain healthy skin barrier function, and reduce the impact of these chronic conditions on daily life.

This includes risk assessment based on itinerary, advice on food and water safety, insect bite prevention (malaria, dengue, Zika), altitude sickness prevention, and administration of necessary routine and travel-specific vaccinations (e.g., Hepatitis A/B, Typhoid, Yellow Fever if certified).

Is seeing a family doctor (Médecin de famille) covered by Régie de l&#x27;assurance maladie du Québec (RAMQ) in QC?

Medically necessary visits to a family doctor are typically covered by the Régie de l'assurance maladie du Québec (RAMQ) for eligible residents with a valid provincial health card. However, some services, such as cosmetic procedures, most travel medicine consultations, sick notes, insurance forms, and driver's medicals, may not be covered and might have an associated fee. Please confirm with Clinique Fort Chambly if you have questions about specific non-insured services or potential fees.

What happens if Dr Gnass determines I need to see a medical specialist?

If Dr Gnass determines that your condition requires the expertise of a medical specialist (e.g., a cardiologist, dermatologist, surgeon, psychiatrist), he will discuss the reasons with you and initiate a referral. This usually involves Dr Gnass sending a formal referral letter along with your relevant medical information to the specialist's office. Wait times for specialist appointments can vary significantly depending on the specialty and the urgency of your condition. The staff at Clinique Fort Chambly will typically inform you once the referral has been sent, and in most cases, the specialist's office will contact you directly to schedule an appointment. Please follow up with Clinique Fort Chambly if you haven't heard from the specialist's office within a reasonable timeframe, as advised by Dr Gnass.

How can I find a family doctor (Médecin de famille) in QC who is accepting new patients?

Finding a family doctor in QC who is accepting new patients can be challenging. You can check the website of the Collège des médecins du Québec, which often has a "Find a Doctor" tool or list.

What does 'preventative care' involve with a family doctor like Dr Gnass?

Preventative care with Dr Gnass focuses on keeping you healthy and identifying potential health problems before they become serious or cause symptoms. This involves a range of services tailored to your age, gender, and risk factors, such as routine check-ups (periodic health exams), age-appropriate cancer screenings (e.g., Pap tests, mammograms, colon cancer screening, PSA discussions), immunizations (flu shots, travel vaccines, routine boosters), blood pressure and cholesterol checks, screening for diabetes, counseling on healthy lifestyle choices (diet, exercise, smoking cessation, responsible alcohol use), and risk assessments for various conditions. The primary goal is to prevent illness, detect diseases early when they are most treatable, and promote your long-term health and well-being.

What exactly is a family doctor (Médecin de famille) and what is their role?

A family doctor, often called a general practitioner (GP), is a medical doctor specializing in comprehensive primary healthcare for individuals and families across all ages and life stages. They serve as your first point of contact for most health concerns, offering preventative care (like check-ups, immunizations, and health screenings), diagnosing and treating acute illnesses (such as infections or minor injuries), managing chronic conditions (like diabetes, hypertension, or asthma), providing mental health support, and coordinating your care by referring you to specialists when necessary. A key aspect of their role is building long-term relationships with patients to promote overall health and well-being.
